VEGA2: Dust Particle Impact Detector Data from Cometary Coma

The SP-2 experiment on the Vega spacecraft studied the spatial and mass distributions of dust particles in a cometary coma. It covers a mass range from 1.e-16 to 1.e-6 grams using impact plasma and acoustic sensors. The data is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Modeling spatial distribution of dust in a cometary coma based on the sensor data.
• Analyzing the mass spectrum of cometary dust particles across the 1.e-16 to 1.e-6 gram range.
• Comparing detection methodologies using the described impact plasma and acoustic sensors.
• Calibrating dust flux models for similar space missions.

Strengths

• Covers an exceptionally broad mass range for dust particles, from 1.e-16 to 1.e-6 grams.
• Data originates from a dedicated space mission experiment (Vega SP-2).
• Uses dual sensor types (impact plasma and acoustic) for detection.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
